I interviewed for a backend role at a mid-sized company (question recap)

I applied as a candidate with 3 years of experience. The first round was technical, and the second was an executive interview. The CS portion was heavier than expected, so I was caught off guard.

The questions I got were: how to find queries that aren't using an index, what phenomena occur at each transaction isolation level, and where you start looking when an internal API slows down.

The executive interview was mostly personality/behavioral, so it was comfortable. But when I answered honestly to "Why do you want to change jobs?" the reaction was ambiguous. They said the results will come out this week, and I'm nervous.
